[Sustak pharmacodynamics in effort stenocardia].
Sustak pharmacodynamics was studied in 32 patients with stable angina pectoris of effort during acute tests with dosaged physical exercises repeated a tone-hour intervals. The results were compared with those in placebo. It is shown that the duration and pronounced character of the antianginal sustak effect varies widely in different patients. The maximum effect of the drug in a dose of 6.4 mg was encountered one hour after medication and was characterized by reduced depression of the ST segment by 54% during physical exercise and alleviation of the pain syndrome. The drug caused a statistically significant reduction of arterial pressure, an increase in the pulse rate at rest and a decrease of this value during exercise. The antianginal effect of sustak was particularly manifest in patients with low tolerance of physical exertion and in patients in whom the attack of angina pectoris was attended by marked dyspnea.
